Great Yeast
So far I'm really impressed with Barbarian, and Imperial Yeast in general. I've used Barbarian 3 times now, and it may be my favorite yeast for hop forward beers - I plan on experimenting with it for other styles as well. 200B cells per package is nice.

Used on an IPA that started at 1.072 and this yeast plowed through it, taking it down to 1.015 within a week. Another week to let it clean things up and I have an IPA that is awesome!

Stone Fruit
I fermented an ESB with this strain and really liked the results. It accentuated the stone fruit characteristics of the First Gold hops. I plan to brew a slightly different version of this ESB recipe again with only this strain to let the peachy, apricoty esters shine. I fermented at 67-68F for the first 3 days and then slowly stepped up by one degree per day to 72 to finish attenuation.

great yeast supplier for conan
Have used others that don't attenuate well on the first generation and are finicky but the imperial was great. No attenuation problems and made a great NEIPA.

Worked great
I was a little concerned give the not so great reviews but I'm glad I tried it. Worked awesome in my topper clone. Didn't have any issues with the can. Attenuation and lag time were awesome. Would use again.

First time using this yeast. I used it in a North Eastern IPA. It was the perfect match for the style and what I was looking for. Nothing but great reviews from everyone. They all take a drink and then the WOW face.
